Description

Technical Field

[0001] This utility model relates to the field of chemical equipment and process control, and in particular to a control device for an ionic liquid storage tank. Background Technology

[0002] Ionic liquid storage tanks are used to safely and stably store ionic liquids, a special chemical substance. They effectively prevent ionic liquids from deteriorating due to environmental factors, avoid leaks or equipment damage caused by their corrosive and hygroscopic properties, ensure production continuity, and achieve efficient access and recycling of ionic liquids through standardized storage. They also reduce safety risks by preventing ionic liquids from reacting with air, water, or other substances to produce hazards. This is crucial for safe production and environmental compliance in industries such as chemical and energy that rely on ionic liquids.

[0003] The control device of the ionic liquid storage tank works in concert with multiple systems. The temperature control system regulates the temperature with a jacket or electric heating belt, and achieves closed-loop control with the help of sensors and PLC. The nitrogen system maintains a slight positive pressure inside the tank to isolate water and oxygen. The filter intercepts impurities. The liquid level and pressure sensors are linked with valves to regulate the flow rate. The PLC integrates various parameters to achieve automated operation and safety interlocks, ensuring a stable ionic liquid storage environment.

[0004] In the prior art, the control device of some ionic liquid storage tanks usually discharges the internally stored liquid through the outlet when discharging liquid. This makes it difficult to control the liquid discharge volume. When the liquid level is too low, the unstable flow rate will draw in air, which will damage the nitrogen protection environment and increase the risk of water and oxygen pollution. Therefore, a control device for ionic liquid storage tanks is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a control device for an ionic liquid storage tank, which aims to improve the problem in the prior art that it is not easy to control the liquid output, and when the liquid level is too low, air may be drawn in due to unstable flow rate, which will damage the nitrogen protection environment and increase the risk of water and oxygen pollution.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A control device for an ionic liquid storage tank includes a support leg, a mounting plate fixedly connected to the top of the support leg, a tank body fixedly connected to the top of the mounting plate, a discharge port fixedly connected to the outer wall of the tank body, a limiting groove formed on the inner wall of the discharge port, a rotating plate slidably connected to the inner wall of the limiting groove, a plurality of round rods fixedly connected to the inner wall of the rotating plate, a plurality of sliding grooves formed on the inner wall of the discharge port, and a filter assembly for filtration installed on the outer wall of the discharge port.

[0008] As a further description of the above technical solution:

[0009] The filter assembly includes a filter tube, the bottom of which contacts the top of the outlet. A connecting block is fixedly connected to the bottom of the filter tube, and the outer wall of the connecting block is rotatably connected to the inner wall of the outlet.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the rotating plate is rotatably connected to the inner wall of the discharge port, and the outer walls of the plurality of round rods are slidably connected to the inner walls of the plurality of sliding grooves;

[0012] As a further description of the above technical solution:

[0013] Each of the round rods has a baffle fixedly connected to its outer wall. The outer wall of the baffle is slidably connected to the inner wall of the discharge port, and the outer wall of the baffle is in contact with the outer wall of the rotating plate.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the filter tube is fitted with a threaded tube, and the outer wall of the threaded tube is threadedly connected with a threaded cap.

[0016] As a further description of the above technical solution:

[0017] The inner wall of the threaded cap is provided with a groove, and a filter screen is detachably connected to the groove of the threaded cap.

[0018] As a further description of the above technical solution:

[0019] A sealing ring is detachably connected to the groove of the threaded cap, and the inner wall of the sealing ring is in contact with the outer wall of the filter screen.

[0020] As a further description of the above technical solution:

[0021] The outer wall of the filter screen is in contact with the top of the filter tube, and the outer wall of the sealing ring is in contact with the top of the filter tube.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by rotating the rotating plate, the baffle on the round rod is driven to open to both sides. The opening and closing size of the baffle is adjusted by the sliding of the rotating plate in the limiting groove. This allows for flexible control of the outflow rate of the ionic liquid, preventing the high viscosity ionic liquid from producing pulsed output due to a fixed flow rate, which could cause pipeline pressure fluctuations or even local turbulence carrying air bubbles, thus affecting purity.

[0024] 2. In this utility model, the sealing ring and filter screen can be replaced by rotating the filter tube and threaded cap. After replacement, the filter tube is reconnected to the outlet to restore the filtration function, thereby completing the replacement of the filter screen and sealing ring inside the filter tube. This prevents the filter from becoming clogged due to inconvenient replacement, which would increase pipeline resistance and energy consumption, and also prevents the aging of the sealing ring from increasing the risk of leakage.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 4 and Figure 5An embodiment of this utility model provides: a control device for an ionic liquid storage tank, including a support leg 1, the support leg 1 for fixing a mounting plate 2, the mounting plate 2 fixedly connected to the top of the support leg 1, the mounting plate 2 for mounting a tank body 3, the tank body 3 for storing ionic liquid, a discharge port 4 fixedly connected to the outer wall of the tank body 3 for the ionic liquid to flow out from the tank body 3, a limiting groove 15 is formed on the inner wall of the discharge port 4 for limiting the rotation of a rotating plate 5, the rotating plate 5 is slidably connected to the inner wall of the limiting groove 15, the rotating plate 5 is used to fix a round rod 7, a plurality of round rods 7 are fixedly connected to the inner wall of the rotating plate 5 for fixing a baffle 8, a plurality of sliding grooves 6 are formed on the inner wall of the discharge port 4 for the sliding of the round rods 7, and a filter assembly for filtration is installed on the outer wall of the discharge port 4;

[0034] The outer wall of the rotating plate 5 is rotatably connected to the inner wall of the outlet 4. The outer walls of the multiple round rods 7 are slidably connected to the inner walls of the multiple sliding grooves 6. The outer walls of the multiple round rods 7 are all fixedly connected to baffles 8. The baffles 8 are used to control the flow rate of the ionic liquid. The outer wall of the baffles 8 is slidably connected to the inner wall of the outlet 4. The outer wall of the baffles 8 is in contact with the outer wall of the rotating plate 5.

[0035] Reference Figure 2 and Figure 3 The filter assembly includes a filter tube 9, which is used for the initial filtration of ionic liquids. The bottom of the filter tube 9 is in contact with the top of the outlet 4. A connecting block 10 is fixedly connected to the bottom of the filter tube 9. The connecting block 10 is used to connect the filter tube 9 and the outlet 4. The outer wall of the connecting block 10 is rotatably connected to the inner wall of the outlet 4. A threaded tube 14 is sleeved on the outer wall of the filter tube 9. The threaded tube 14 is used to connect with a threaded cap 11. The outer wall of the threaded tube 14 is threadedly connected to the threaded cap 11. The threaded cap 11 is used to install the sealing ring 12 and the filter screen 13.

[0036] The inner wall of the threaded cap 11 has a groove, and a filter screen 13 is detachably connected to the groove of the threaded cap 11. The filter screen 13 is used for secondary filtration of ionic liquid. A sealing ring 12 is detachably connected to the groove of the threaded cap 11. The sealing ring 12 is used to prevent leakage of ionic liquid during filtration. The inner wall of the sealing ring 12 is in contact with the outer wall of the filter screen 13, the outer wall of the filter screen 13 is in contact with the top of the filter tube 9, and the outer wall of the sealing ring 12 is in contact with the top of the filter tube 9.

[0037] Working principle: When it is necessary to adjust the flow rate of the ionic liquid in tank 3, the operator manually rotates the rotating plate 5 and slides it in the limiting groove 15. The sliding of the rotating plate 5 drives the round rod 7 to slide smoothly in the sliding groove 6, so that the baffle 8 fixed on the round rod 7 opens to both sides. At this time, the opening and closing size of the baffle 8 can be driven by the sliding of the rotating plate 5 in the limiting groove 15, thereby realizing the flexible control of the ionic liquid flow rate. This prevents the waste of raw materials and the imbalance of the reaction system caused by excessive flow, and also prevents the decrease in production efficiency caused by insufficient flow, ensuring that the entire production process is stable and efficient.

[0038] When it is necessary to replace the filter screen 13 and sealing ring 12 inside the filter tube 9, the operator rotates the filter tube 9, and then the connecting block 10 on the filter tube 9 separates from the discharge port 4, allowing the filter tube 9 to be removed. Then, the threaded cap 11 at the other end of the filter tube 9 is rotated, and then the threaded cap 11 separates from the filter tube 9, allowing the sealing ring 12 and filter screen 13 inside the threaded cap 11 to be replaced. After the replacement is completed, the above steps are reversed to reconnect the filter tube 9 to the discharge port 4, so that the filter can be used normally. This completes the replacement of the filter screen 13 and sealing ring 12 inside the filter tube 9, preventing the need for long-term machine downtime for disassembly during replacement, which would disrupt the production rhythm and reduce equipment utilization.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
